Edit HTTP Headers for Safari

Edit HTTP Headers for Safari is a Safari extension that lets you create rules to set or remove HTTP request headers for specific websites.

Use it when you need Safari to send a custom header before a page, script, image, iframe, stylesheet, font, media file, or XHR/fetch request loads.

Features:

· Create Custom Header Rules: Add HTTP header rules for the websites you choose.

· Set Request Headers: Replace or add a header value before Safari loads a matching request.

· Remove Request Headers: Remove selected headers from matching requests when you do not want them sent.

· Per-Website Rules: Create different header rules for different domains.

· Resource Type Controls: Choose exactly where a rule applies, including main pages, iframes, scripts, images, stylesheets, fonts, media, and XHR/fetch requests.

· iCloud Sync: Keep your header rules synced across iPhone, iPad, and Mac.

· Privacy-first design: No data collection, tracking, or logging, your browsing stays completely private.

· Multilingual support: Use the extension in multiple languages for a globally friendly experience.

· Clean, user-friendly UI: Enjoy a streamlined design that integrates smoothly into your workflow.

· Seamless Safari integration: Built to work across Safari on macOS, iOS, and iPadOS.
